CLOTHES-VRINGER.

Application filed April 1, 1 916.

1 b all whom it may concern.

Be it known that I, JOHN F. HnMnNwAY, a citizen of the United States,residing at New York city, in the county of New York and State of NewYork, have invented certain new and useful Improvements in Clothes-lVi-ingers, of which the following is a specification, referencebeing had therein to the accompanying drawing.

This invention relates to certain new and useful improvements in clotheswringers, and more particularly to pressure releasing means for thepressure rolls, the object being to provide means for releasing the topbar of the wringer frame carrying the pressure screws so as toinstantaneously release the pressure on the pressure roll.

Another object of my invention is to provide a wringer with a movabletop bar which is held in position with the slotted upper ends of theside bars by a bowed spring, the ends of which extend into thehorizontal slots of the vertically disposed portions of U-shaped member,carried thereby, said spring being reduced in width adjacent the ends sothat when the reduced portions are moved into vertical alinement withthe vertically disposed slots which register with the horizontallydisposed slots of the vertically disposed members, the top bar" will beallowed a limited upward movement.

Other and further objects and advantages of the invention will behereinafter set forth and the novel features thereof defined by appendedclaims.

In the drawing, Figure 1 is a side elevation of a wringer showing theapplication of my improved construction of pressure releasing meansthereto. Fig. 2 is a top plan view, and Fig. 3 is an end elevation.

Like numerals of reference refer to like parts in the several figures ofthe drawing.

In carrying out my invention I employ a wringer frame composed of a pairof slotted side bars 1 and 2 connected together adjacent their lower endby cross bars 3 and provided with superposed bearings i and 5 in whichare mounted shafts 6 and 7 carrying cooperating pressure rolls 8 and 9,said shafts being provided with gears, not shown, and inclosed bycasings 10.

Mounted on top of the upper bearings 5, is a cross bar 11 which isslidably mounted within the slotted portions of the side bars 1 and 2and upon which the free ends of a pressure spring 12 are mounted, saidspring Specification of Letters Patent.

being carried by a pressure bar 13 which is provided with bearing plates14 adjacent the ends thereof.

Slidably mounted within the upper ends of the slotted portions of theside bars 1 and 2 is a top bar 15 provided with threaded boxes 16adjacent its ends in which are mounted the threaded portions of pressurescrews 17 which engage the bearings 14 of the pressure bar 13 so as toadjust the pressure on thepressure rolls.

Secured to the upper ends of the side bars 1 and 2 of the wringer frameare U-shaped members 18 which are provided with vertically disposedportions 1.9 having horizontally disposed slots 20 from which extendvertically disposed slots 21 whereby a substantially inverted T-shapedslot is formed in each vertically disposed portion.

Arranged on the top bar 15 is a bowed spring 22 which is provided withsubstantially horizontally disposed end portions having oppositelydisposed notches forming substantially T-shaped portions 23 at the endsof the bowed spring, the heads of the T being adapted to normally restwithin the horizontally disposedslots of the vertically disposedportions 19 of the U-shaped members so as to prevent the top bar 15 frommoving vertically whereby the same is held in rigid position within theside bars 1 and 2 of the wringer frame so as to allow the pressurescrews 17 carried thereby to exert a pressure on the pressure bar 13.The ends of the springs are slotted, as shown at 2 1-, through which thepressure screws 17 pass so as to allow the spring to have free movementin respect to the screws whereby the top bar when released, will beallowed to move vertically.

When the pressure releasing mechanism is in the position shown in Figs.1 and 2, and is desired to instantaneously release the pres sure on thepressure rolls, by striking the bowed spring 22, the same will beelongated so as to force the heads of the T-shaped ends 23 out throughthe slots 20 which will bring the reduced portions or the stems of the Tin vertical alinement with the vertical slots 21 of the extensions 19 soas to allow the top of the springs to move vertically within the slots21 which allows the top bar to move vertically to release the pressureon the pressure roll.

From the foregoing description, it will be seen that I have provided aclothes wringer in which the top bar is normally held in position withthe side bars of the wringer frame by a bowed spring havingsubstantially T-shaped ends which are adapted to cooperate withsubstantially T-shaped slots formed in the vertically disposed portionsof the members carried by the side bars so as to allow the top bar tohave a limited vertical movement when the reduced portions of thesprings are brought into alinement with the vertically disposed slotswhich will instantaneously release the pressure on the pressure rolls ofthe wringer, and at the same time will prevent the top bar fram becomingdetached from a wringer frame.

I claim:

1. A wringer comprising a frame, having pressure rolls and pressuremounted therein, a movably mounted top bar mounted within said frame,U-shaped members carried by the side bars of said wringer frame havingvertically disposed portions provided with substantially invertedT-shaped slots, pressure screws carried by the top bar, a bowed springprovided with slots to receive said pressure screws, said bowed springhaving horizontally disposed T-shaped ends mounted within the slots ofsaid vertically disposed portion and normally holding said top bar inposition within said frame.

2. A clothes wringer comprising a frame having a movably mounted top barcarrying pressure screws, members carried by the side bars of said frameprovided with vertically disposed portions having inverted T-shapedslots, and a bowed spring carried by said top bar and havingsubstantially T-shaped ends cooperating with said slots for holding saidtop bar in position in said fame and for allowing said top bar to movevertically by the lateral movement of the ends of said spring.

3.
